The Philodendron silver sword (Philodendron hastatum ‘Silver Sword’) is a gorgeous climbing Philodendron that is beloved for its pale, silvery green color and arrow-shaped leaves. As it matures, its leaves become increasingly elongated and tri-lobed. Paired with its climbing growth habit, this impressive foliage adds an instant tropical feel to any room. While it is native to rainforests across South America, this Philodendron has become popular as a houseplant. Before adding one to your home, pet owners and parents of young children should be aware that like all Philodendrons, the Philodendron silver sword is considered toxic to pets and humans if ingested.
